AbstractObjectiveWe assessed the prevalence, patterns and predictors of dietary supplement use among participants of the databank and biorepository (DBBR) at a comprehensive cancer centre in western New York.DesignArchived epidemiological questionnaire data were obtained from the DBBR at Roswell Park Cancer Institute. Descriptive statistics and logistic regression explored the prevalence, patterns and predictors of lifetime use of four common supplements (multivitamins, vitamin C, vitamin E and calcium) and use of multivitamins, sixteen single vitamins/minerals and eighteen herbal/specialty supplements within the previous 10 years.SettingWestern New York, USA.SubjectsDBBR participants (n 8096) enrolled between December 2003 and July 2012 were included in these analyses: 66·9 % (n 5418) with cancer, 65·6 % (n 5309) women, mean age for patients v. cancer-free controls 59·9 (sd 12·6) years and 50·7 (sd 15·4) years, respectively.ResultsOverall, 54·4 % of DBBR participants reported lifetime use of one or more supplements and 63·1 % reported use of one or more supplements within the previous 10 years (excluding multivitamins). Multivitamin use was high in this sample (lifetime: 64·1 %; 10 years: 71·3 %; current: 51·8 %). Supplementation was higher among cancer-free controls than cancer patients. Vitamin C, calcium and fish oil were the most common single vitamin, mineral and specialty product, respectively.ConclusionsA consistently high and increasing proportion of dietary supplement use over time remains clear. Supplementation is prevalent among cancer patients and may even be higher than predicted in cancer-free individuals. Further studies should assess the safety and efficacy of specific supplements in reducing disease risk.

Dietary Supplement Use

Supplement use was surveyed in a convenience sample of persons who exercised regularly at a Long Island, NY gym. Participants, age at least 18 y, completed anonymous questionnaires. A majority (84.7%) took supplements. Many consumed multivitamin/minerals (MVM; 45%), protein shakes/bars (PRO; 42.3%), vitamin C (34.7%), and vitamin E (VE; 23.4%) at least 5 times per wk. Other dietary supplements were used less frequently or by fewer participants. Ephedra was consumed by 28% at least once per wk. Choices and reasons for dietary supplement use varied with age of the participant. More of the oldest consumed MVM or VE, while those 45 y or younger chose PRO. Those younger than 30 consumed creatine more frequently. The oldest participants took supplements to prevent future illness, while others took supplements to build muscle. The reason for committing to an exercise program influenced supplement use. Bodybuilders more frequently consumed PRO, creatine, and ephedra compared to those exercising for health reasons.

Dietary Supplement Use

Vitamin and mineral supplement use is thought to be common among the 10 million adults in the United States who have been diagnosed with cancer; however, well-conducted studies of this topic are sparse. Moreover, the biologic effects of supplement use among cancer survivors are not well established and not necessarily beneficial. We present a systematic summary of studies published between 1999 and 2006, 32 in total, addressing vitamin and mineral supplement use among US adult cancer patients and survivors. Supplement use is widespread among cancer patients and longer-term survivors. In studies combining different cancer sites, 64% to 81% of survivors reported using any vitamin or mineral supplements and 26% to 77% reported using any multivitamins. In contrast, approximately 50% of US adults use dietary supplements and 33% use multivitamin/multimineral supplements. Between 14% and 32% of survivors initiate supplement use after diagnosis, and use differs by cancer site. Breast cancer survivors reported the highest use, whereas prostate cancer survivors reported the least. Higher level of education and female sex emerged as factors most consistently associated with supplement use. Up to 68% of physicians are unaware of supplement use among their cancer patients. These results highlight the need for further studies of the association between dietary supplement use and cancer treatment toxicity, recurrence, survival, and quality of life to support evidence-based clinical guidelines for dietary supplement use among cancer patients and longer-term survivors.

Abstract Background A variety of dietary supplements are commercially available. However, the efficacy and safety of dietary supplement use in children are not well established. Understanding dietary supplement use is important for developing public health policy regarding dietary supplements. This study aimed to investigate the types of dietary supplements used and characteristics of dietary supplement users among Japanese elementary school children. Method We conducted a cross-sectional web-based questionnaire study. Dietary supplement use, socio-demographics, and health-related behaviors were assessed through mother-reported questionnaire. Types of dietary supplements were identified based on ingredient using product barcodes and brand names. Multivariate logistic regression analysis was conducted to investigate the socio-demographics and health-related behaviors associated with supplement use. Results Among 4933 children, 333 (6.8%) were identified as dietary supplement users. The most common supplement was amino acids or protein (1.4%), followed by n–3 fatty acids or fish oil (1.0%), probiotics (1.0%), multivitamins (0.9%), multivitamin-minerals (0.8%), and botanicals (0.8%). Overall, any dietary supplement use was significantly associated with the highest frequency of sports participation (odds ratio [OR], 2.58; 95% confidence interval [CI], 1.65–4.02), highest household income (OR, 1.87; 95% CI, 1.13–3.10), highest maternal educational level (OR, 1.82; 95% CI, 1.31–2.52), and male sex (OR, 1.38; 95% CI, 1.09–1.75). The highest frequency of sports participation was significantly associated with higher odds of use of amino acids or protein (OR, 6.06; 95% CI, 1.78–20.6) and multivitamins (OR, 3.56; 95% CI, 1.11–11.5), compared to the lowest frequency of sports participation. Conclusion This study showed that Japanese children primarily use non-vitamin, non-mineral supplements. Non-vitamin, non-mineral supplements should thus be included in future studies aimed at monitoring dietary supplement use. We also found that dietary supplement use in children was associated with sports participation. Guidelines for dietary supplement use for children, in particular sport participants, are needed.
